These duets really work for average piano students because of the brilliance of the arranger, Robert Vandall. He's a pianist and teacher who understands how students think at the piano! They're not too hard or involved; so they're perfect for young pianists-in-training! The primo and secondo parts are of equal difficulty and interest. Melodies are passed between the two parts. The series includes such sacred carols as Away in a Manger; The Little Drummer Boy; Santa Claus Is Comin' to Town; Ukrainian Bell Carol; Frosty the Snowman and O Come, All Ye Faithful.
